permissible power which may be dissipated continuously, at normal operating conditions
ADA084ADA084power loss of a component with losses proportional to I² during the state under load at maximum possible continuous rms current (= rated current) and measured at rated ambient temperature and at rated frequency
reference to a document depicting the power loss of a component with losses not proportional to I² during the state under load up to the maximum possible continuous rms current (= rated current) and measured at rated ambient temperature and at rated frequency
amount of electric conducting routes of an object carrying the current, contributing to thermal losses in type and routine tests
required minimum current derating factor of an electric-electronic or electromechanical component, for a specified ambient temperature higher than the rated temperature
average ratio of the duration of energization to the total period in which intermittent or continuous or temporary duty takes place
thermal power loss caused by the over- current in a short-circuit or in a situation equivalent to a short-circuit measured at given duration and at rated ambient temperature
power consumption when the item is in a non-operating up state during non-required time and measured at rated ambient temperature and rated frequency
power loss of a component with linear losses proportional to I during the state under load at maximum possible continuous rms current (= rated current) and measured at rated ambient temperature and at rated frequency

- Note
- If the output power and/or input power is electric, active power is meant.
- Remark
- 1 This collection provides a overview of power losses of a component during all operational stages defined in IEC 62744, independent whether the power consumption is caused by unintended losses or whether it is intended, e.g. for radiation or heating purposes. 2 The properties can be applied also for calculation of the energy efficiency of a component being defined by: ratio or other quantitative relationship between an output of performance, service, goods or energy, and an input of energy [SOURCE: ISO 50001:2011, 3.8] 3 IEC 61439-1 provides guidance to the calculation of power losses in closed assemblies, e.g. cubicles, when having the losses of the assembled components.
